An Iran fake missile launch caught the attention of President Donald Trump who tweeted about the incident late Saturday.

Iranian state television released a video Friday of a supposed launch of a medium-range missile shortly after it was shown off at a Tehran military parade. U.S. officials said, though, that the video was seven months old taken from a failed attempt in late January, Fox News reported.

"Iran has released footage of the successful test-launch of its new ballistic missile, Khorramshahr, a few hours after it was unveiled during a military parade in the capital city of Tehran," state-run Press TV said, according to CNN.

An official told CNN, though, that electronic signals of a ballistic missile launch would have been picked up by various U.S. assets in the region that keep tabs on Iran's weapons activities.

"As far as we can see, it did not happen." the official told CNN.

During his speech to the United Nations on Sept. 19, Trump harshly criticized Iran, for allegedly sponsoring terrorism, and threatened to end the U.S.-led deal with Iran over its nuclear program, negotiated by the Obama administration.

"We cannot let a murderous regime continue these destabilizing activities while building dangerous missiles, and we cannot abide by an agreement if it provides cover for the eventual construction of a nuclear program," Trump said in his U.N. speech.

"The Iran Deal was one of the worst and most one-sided transactions the United States has ever entered into. Frankly, that deal is an embarrassment to the United States, and I don't think you've heard the last of it -- believe me. It is time for the entire world to join us in demanding that Iran's government end its pursuit of death and destruction," Trump continued.

Iranian President Hassan Rouhani, who spoke at the U.N. the following day, said that its country's missiles are "solely defensive" in nature, Fox News reported.

"We never threaten anyone, but we do not tolerate threats from anyone," Rouhani had said, according to Fox News.
